It seems that my PC may be experiencing a reboot on its own. This has happened in the past, and I thought that it was weird but I couldn't determine why. I now think I know why because I am crunching some SRBase WU's again, and it has happened again. When I went back to my last unusual restart it was at a time when I was crunching SRBase WU's. Has anyone else had unusual reboots with WU's being crunched for any particular projects?
My event log just shows a unexpected reboot, and my APC data shows that it was not a power outage that might have caused it.

I got in, cool, more work.

Can you check your temps from the CPU? In BIOS there is a setting with 90°C where the PC is shutting down if the CPU is reaching this value.
